Everything

• There are 3 types of muscles: cardiac, smooth and skeletal
• Cardiac muscle make up the heart walls and is responsible for controlling the heart
• smooth muscles are found in the intestines and blood vessels, are involuntary
• Skeletal muscles: muscles attached to the bone and allow you to move and perform, are voluntary
• Where are smooth muscles found?

  In the intestines and blood vessels
• where are cardiac muscles found?

  In the heart
• Which muscles are involuntary

  Cardiac and smooth muscles
• what muscles are voluntary

  Skeletal
• Muscles creating the movemtn is known as Agonist
• Muscles that relaxes are known as the Antagonist
• Muscles that contract to hold the surrounding bones still are known as stabilizers
• Movement is when the muscles contract or Shorten. Muscles work in pairs so when 1 muscle contracts the other relaxes. This is known as Reciprocal Inhibition.
• Superior is towards/closer to the head
• Inferior is further/ away from the head
• Anterior is towards the front of the body
• Posterior is towards the back of the body
• Medial is closer to the midline of the body
• Lateral is further from the midline of the body
• Proximal is closer to the attachment point
• Distal is further from the attachment point
• Define Superior?

  closer to the top/head
• Define Anterior

  Towards the front of the body
• Define Posterior

  Towards the back of the body
• Define Medial

  Closer to the midline of the body
• Define Lateral

  further away from the midline of the body
• Define Proximal

  A body part closer to the attachment point
• Define Inferior

  Closer to the bottom/feet
• what are the 4 roles of the skeletal system?

  body movement, framework and protection, mineral storage, production of red blood cells.
• what does framework and protection do

  assist us to stand up right and to protect vital organs
• where is the production of red blood cells

  in bone marrow inside of long bones
• how many bones are in the vertebral columm

  33, 24 unfused and 9 fused
• Cervical has 7 unfused bones and is responsible for supporting the neck
• Thoracic has 12 unfused bones allowing connection between spine and ribcage as well as protects heart and lungs
• Lumbar has 5 unfused bones, largest vertebrae to hold the body's weight
• Sacrum has 5 fused bones that are fused to the pelvis and distributes weight
• Coccyx has 4 fused bones, provide site for muscle to attachment of the lower body
• name all 5 parts of the vertebral column (in order)

  Cervical, Thoracic, Lumbar, Sacrum, Coccyx
• how many type of bones are there?

  5
• name the 5 type of bones

  short bones, long bones, sesamoid bones, irregular bones
• define what short bones are

  cube like in shape (similar width and length)
